3 Claims. (Cl. 145-1) This invention relates to tools used by carpenters particularly in building construction wherein it is desired to draw or cinch wall, floor, and ceiling boards against formerly applied boards without leaving cracks between the boards, and in particular a tool having a handle with a board gripping section extended from the handle and with means for anchoring the tool on framing material as the tool is actuated with a hammer to cinch a board against studding and also against a formerly applied board.

The purpose of this invention is to provide a tool adapted to be freely mounted on a two by four or other studding or framing wherein the tool is adapted to be positioned against the edge of the board and readily actuated by a handle to draw the board against the formerly applied board.

Various types of devices have been provided for cinching up flooring, wall board and boards used on partitions, walls, ceilings and the like, however, such devices are comparatively heavy and it is difiicult for an operator, such as a carpenter to move the tool from one joist to another and it is particularly diflicult to carry the tool from one job to another.

Clamping or cinching up tools of this type are designed primarily for use on horizontally disposed elements, such as floors, however, because of the construction thereof it is ditficult to use tools of this type on a vertically disposed wall or ceiling.

With this thought in mind this invention contemplates a hand actuated tool having a substantially C-shaped body with a handle extended from one end and with a plurality of teeth extended from an edge positioned to engage the surface of a stud whereby with the device anchored by the teeth on a stud it is adapted to be actuated by a hammer for drawing one board up against another.

The object of this invention is, therefore, to provide a board cinching tool for drawing one board against another in which the tool is adapted for use on floors, vertically disposed walls, and also on ceilings.

Another object of the invention is to provide a board cinching tool that is adapted to be used on studding and other framing without attaching the device to the studding or framing with screws, bolts, or other fastening elements.

A further object of the invention is to provide an improved board cinching tool that is adapted to be freely positioned over studding and that is adapted to be actuated to draw one board against another in which the device is of a simple and economical construction.

With these and other objects and advantages in view the invention embodies a substantially C-shaped body having teeth in one end and also having a flange with a lip on the edge thereof extended from the end on which the teeth are positioned, and with a handle extended from the end opposite to the end on which the teeth, flange and lip are positioned.

Other features and advantages of the invention will appear from the following description taken in connection with the drawing, wherein:

. United States Patent stud in broken lines and in a position .in which it is *ing' one board against another in full lines.

Figure 2 is a side elevational view of the tool looking toward the open side of the body portion thereof.

Figure 3 is a View, similar to that shown in Fig. 1, looking upwardly toward the under surface of the tool.

Figure 4 is a cross section through the body of the tool taken on line 4-4 of Fig. 2.

Figure 5 is a view showing a cross section through a portion of a wall illustrating the use of the device with the tool in the position in which it is positioned over a hold- Referring now to the drawing wherein like reference characters denote corresponding parts the improved board cinching tool of this invention includes a body, C-shape in plan having a rear wall or web 10, end walls or arms 11 and 12, teeth 13 on the upper edge of the end wall 12, a flange 14- extended angulariy from the lower edge of the wall 12 and having a lip 15 on the extended edge and a handle including a stem 16 and a gripping sleeve 17 we tended from the end wall 11 and positioned perpendic ularly to the gripping teeth 13 of the wall 12. The extended end of the stem 16 is peened over, as shown at the point 18 in Fig. 1 to prevent the sleeve 17 being accidently displaced from the stem.

The front of the body, which is substantially open is provided with small plates 19 and 20, the plate 19 having a beveled edge 21 and the plate 20 a similar beveled edge 22, the angles of the edges 21 and 22 being such that with the tool held in the position indicated by the broken lines 23 in Fig. 5 the edges 21 and 22 correspond with end surfaces of a two by four or other stud, as indicated by the numeral 24. By this means the tool may readily be placed over a stud or other frame member and moved downwardly to a horizontal position with the lower surface 25 seated upon the upper edge 26 of a board 27.

In use the device is placed against a stud, such as the stud 24, and above a board such as the board 27, and with the handle 17 urged downwardly with one hand the flange 14 is struck with a hammer held in the other hand driving both the tool and board 27 downwardly forcing the board against a formerly secured board 28 and at the same time driving the teeth 13 which are then positioned at the proper angle into the stud. The tool is held by the handle 17 until the board 27 is secured by nails or the like and the tool is then removed. By this means the board.

27 is cinched against the board 28 which may be posi tioned on a wall, ceiling, floor, or other framing elements. By this means boards, or other building construction units are forced and rigidly held against formerly installed boards and the boards may be retained in this position until they are nailed or otherwise anchored to the joists, or other frame members. After use the tool is released by drawing the handle upwardly and the tool may then be moved on the stud to such a position that another board may be inserted and clamped against the former board.

The board cinching tool of this invention may be provided in different sizes to correspond with studding, floor joists, and other framing members.

The lower edge of the body is provided with a notch 26 which is positioned at the intersection of the lower edge of the rear wall It) and the lower surface of the flange 14 to facilitate positioning the tool on the upper edge of a board, as shown in Fig. 5.

It will be understood that other changes, within the scope of the appended claims, may be made in the design and arrangement of the parts without departing from the spirit of the invention.

What is claimed is:

1. A board applying tool comprising a body substantially C-shaped in plan having arms extended from ends.

-. of-a web ahandle extended from one of said arms and a lip carried by a flange extended from the other of said arms, one side of the body being open and the upper edge of the arm on which the lip and flange are positioned having anchoring teeth thereon and said anchoring teeth being positioned in a plane perpendicular to the handle.

2. A board applying tool comprising a body substantially C-shaped in plan having arms extended from ends of a web, a handle extended from one of said arms and a lip carried by a flange extended from the other of said arms, one side of the body having an opening therein and the edges of the body at the ends of the opening being inclined, the upper edge of the arm from which the flange and lip extends having anchoring teeth thereon and said anchoring teeth being positioned in aplane perpendicular to the handle whereby with the anchoring teeth extended into one edge of a stud downward pressure of the handle cinches a board positioned against the stud'downwardly against a board below.

3. In a board cinching tool, the combination which comprises a body, C-shape in plan having rear and end walls, the front having an extended opening therein, and a handle carried by and extended from one of the end walls, the end wall at the opposite end of the body having anchoring teeth extended from the upper edge and a flange with a lip on the extended edge extended from the lower edge, the lower edge of the body having a board receiving notch therein and the edges of the front at the ends of the opening therein being parallel and inclined to correspend with the end surfaces of a stud or the like to facilitate positioning the tool on the stud and removing the tool from the stud.
